To all whom it may concern.-

Beit known that I, SHERMAN E. LIMPUs, a citizen of the United States,residing at Olathe, in the county of Johnson and State of Kansas,haveinvented a new and useful Wind- Engine, of which the following is aspecification, reference being had to theaccompanying drawings.

This invention has relation to wind-engines designed for use in pumpingwater, and for other purposes; and it consists in the construction andnovel arrangement of parts, as will be hereinafter fully described, andparticularly`pointed out in the claim.

Figure l is a view in perspective of a windengine embodying myimprovements. Fig. 2 is a front elevation. Fig. 3 is a plan View, andFig. 4 is a vertical longitudinal section on the line :t x in Fig. 3.

Referring by letter to the accompanying drawings, A designates thederrick, provided with a circular platform on top, which is providedwith friction-rollers, and a circular rim, B, having inwardly-projectingguidearms C, which holds the turn-table D in place u on the platform.The periphery of the turn-table is also provided with friction-rollers,the 0bject of the rollers in the platform and those in the periphery ofthe turntable being to l` ssen the friction as much as possible. Theturn-table is provided with the bearings for the wheel-shaft E and theframe F for the pitman-rod that engages the pump-rod. The wheel-shaft Eis also provided with a bevel gear-wheel, G, which is adapted to engagea bevel-pinion to drive a rotary shaft when necessary. The frame F isprovided with bearings H, in which the vane I, that regulates thepivoted sections J of the Wind-wheel L, is pivoted. The lower end of thearm I of the regulating-vane I is pivoted to a horizontal rod, M.immediately above the Wheel-shaft E, and this rod M is provided at itsforward end with a forked clutch, N, which engages a grooved spool, O,on the rear face of a disk, P, to the periphery of which the rods Q,that operate the crank-rods R of the wind-wheel sections S, are pivoted.The forward ends of these rods Q are provided with eyes T, which engagethe cranks U of the crank-rods R.

The wheel Vconsists of a hub, W, provided with a series of .radialspokes, X, connected at their outer ends bya rim, Y, which converts thewheel into a balance-wheel. A short distance from the hub of the wheelwooden or iron braces Z are employed to strengthen the spokes.

The wheel-sections S vary in number according as the size of the wheelis increased or diminished in its manufacture. They consist of straight,shorter, lower, or inner rails, a, and curved longer outer rails, b,connected by slats c, placed diagonally across their parallel middlelines.

The curved outer rails of each of the wheelsections S are provided atone end upon their outer faces with metal stops d, which prevent thesections from being turned on their pivots through the spaces betweenthe spokes in the direction of the regulating-vane I, although they areturned edgewise in the opposite direction by the operation of the windwhen it has a power or force greater than the spring e, secured to theframe F, and operating against the vane I to hold thewheel-sectionsnormally in the wind or closed when the wind is not too high.

The tail-vane f is of any desired construe tion, and is secured to theturntable in line with the wheel-shaft, and serves to keep the wheelinthe wind. When the regulating-vane I is forced toward the tail-vane bythe force of the wind, it slides the disk P outward on the wheel-shaftE, and the rods Q operate the crank-rods R and open the wheel-sections,thus slackening the speed of the wind-wheel. Vh en the wind decreases,the spring c forces the vane forward, slides the disk back, and closesthe wheel-sections.

This wind-engine is durable because the wheel-sections are pivotedcentrally on the crank-rods and undue strain does not come upon thesides of the sections. It is simple because there is less machinery init than in others in use, and for this reason it is cheaper. The rim ofthe wheel acts as a balance-wheel and makes the wheel stronger. TheWheel is given a considerabledish, and this adds to its strength andgives it at least one-third more power than if it were not dished. Thesliding disk and grooved spool are of iron.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent of the United States, is-
